How to display the reservation guide screen for a composite broadcast receiver

The present invention relates to a composite broadcast receiver, and more particularly, to a method of displaying a reservation guide screen for displaying reservation information in a composite broadcast receiver that can accommodate a plurality of CATV broadcast signals provided through an external transmission path.

As is well known, satellite broadcasting is capable of receiving broadcast signals from ground stations (broadcasting earth stations) using broadcast satellites in a stationary orbit about 36,000 kilometers above the equator, and receiving them directly from the satellite receiving antennas in each home. The broadcasting system is a broadcasting system in which the selection range of information is greatly expanded compared to the conventional terrestrial or cable broadcasting system.

The satellite broadcast receiver used for the satellite broadcast receives the bit stream provided from the satellite, processes the broadcast signal of the selected channel, and then provides it to a display device (for example, a TV).

In this case, the bit stream provided from the satellite includes various information such as broadcast signals (video data and audio data), event information table (EIT), and time data table (TDT) for each channel.

The satellite broadcasting receiver used for the satellite broadcasting receives the bit stream provided from the satellite, processes the broadcast signal of the selected channel, and then provides the signal to a display device (for example, TV) to display on the screen. The receiver is provided with various menu screens or guide screens for providing the above-mentioned various information and additional functions.

Among these menu screens, there is a reservation guide screen for displaying each program information set by the user (reservation recording, reservation viewing, etc.), and FIG. 5 shows a reservation guide screen provided by the conventional composite broadcast receiver. As an example of the drawing, it will be described with reference to the drawings.

When the user makes a reservation setting for a part of a plurality of satellite broadcasting channels and CATV broadcasting channels provided by the composite broadcasting receiver, each reserved information is stored in a predetermined area of the memory means provided in the receiver. When the user calls the reservation guide screen to refer to this, the reservation guide screen as shown in the drawing is displayed.

That is, each reservation list 501 set by the user is displayed for each time zone, and a reservation guide screen including a title of the broadcast program 503 broadcast in the corresponding time zone of the reserved channel is displayed.

At this time, the program title 503 displayed in the drawing shows the program title of the channel where the cursor is located in the reservation list 501. In the initial state in which the reservation guide screen is displayed by the user's key manipulation, the program title 503 is automatically displayed. As the cursor is located on the first reserved channel, the displayed program title 503 also displays the program name for the first reserved information.

When the user moves the cursor by operating the key input means, the program name for the next reservation information is displayed. The program name is obtained from additional information (program information and channel information, etc.) inserted into the bit stream of the satellite broadcast. Is extracted and displayed.

On the other hand, in recent years, not only satellite broadcasting but also CATV broadcasting method using cable has been rapidly spreading. If a subscriber (that is, one receiver) wants to receive all of these types of broadcasting signals, Because of the different frequency bands, it would be necessary to have separate satellite tuners and cable tuners.

Therefore, in order to accommodate various types of broadcasts as described above, two types of broadcasts are processed through separate signal processing paths (that is, satellite broadcast signal processing paths and cable broadcast signal processing paths). A composite broadcast receiver employing a composite tuner is also being developed.

In addition, such a composite broadcast receiver is provided with a reservation guide screen displaying the reservation information as described above. Unlike the satellite broadcast signal described above, the CATV broadcast signal does not provide additional information for each channel and program. With the reservation guide screen as shown in FIG. 1 displayed, it is not possible to display the program title 503 for the reserved CATV channel.

If the composite broadcast receiver is able to display additional information (eg, program name) for the reserved CATV channel, it may be able to satisfy more diverse user needs.

Accordingly, the present invention has been made in view of the foregoing, and the reservation guide of the composite broadcast receiver capable of displaying detailed information on the reserved CATV channel in the reservation guide screen in which the reservation information for the CATV channel is set in the composite broadcast receiver. It relates to a screen display method.

In order to achieve the above object, the present invention provides a reservation guide screen display method in a composite broadcast receiver that can accommodate a plurality of satellite broadcast channels provided from a satellite and a plurality of cable broadcast channels provided through a transmission path, wherein the receiver Is received from the user, the channel information and the reservation information for the satellite broadcast and cable broadcast in the plurality of cable broadcasting channels, and the pre-store, the guide screen, the respective reservation list for the reservation information and the reservation list And a title column for displaying a corresponding broadcast program title and a cursor for moving the reservation list, wherein the method comprises: when a key signal for displaying the reservation information screen is input, displays the guide screen; Saved reservation information is displayed in the reservation list field. Displaying the cursor at a specific position in the reservation list; A second step of determining whether the reserved list channel corresponding to the position where the cursor is displayed is the satellite broadcasting channel or the cable broadcasting channel; A third step of extracting a program title corresponding to the reserved channel extracted from the satellite broadcast signal in the case of the satellite broadcasting channel and displaying the title in the title column of the guide screen; A fourth step of displaying the previously stored cable broadcasting channel information in the title column of the guide screen when the cable broadcasting channel is determined as a result of the determination; A fifth step of, when the key signal for moving the cursor is input, moving the cursor to a position corresponding to the key signal and displaying the same, and repeatedly performing the process after the second step; And a sixth step of turning off the reservation guide screen and switching the operation of the receiver to a normal viewing mode when a key signal for turning off the reservation guide screen is provided. .

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a composite broadcast receiver suitable for applying a method for displaying a reservation guide screen of a composite broadcast receiver according to an exemplary embodiment of the present invention. The tuner block 102, the MPEG decoding block 104, and the video encoding block are shown. 106, video processing block 108, sync extraction block 110, control block 112, memory block 114, OSD processing block 116, mixer 118, and switching block 120. .

Referring to FIG. 1, the tuner block 102 is based on a tuning control signal provided from a control block 112 to be described later via a line L11, and a broadcast signal receiver (i.e., a satellite reception antenna, a cable, etc.) is not shown. Tunes the broadcast channel selected by the user from the broadcast signal received through the signal and demodulates the tuned broadcast channel signal into the original signal before transmission. In this case, when the satellite broadcast signal is tuned, the demodulated satellite channel signal is transmitted through line L12. The demodulated CATV broadcast channel signal is provided to the video processing block 108 via line L14 when provided to the MPEG decoder block 104 and the cable broadcast signal is tuned.

That is, the tuner block 102 is composed of a composite tuner capable of mode-receiving and tuning satellite and CATV broadcast signals provided through an antenna or transmission line (not shown).

In the MPEG decoder block 104, the compressed and encoded video signal of the tuned satellite broadcast channel provided by the tuner block 102 through the line L12 is compressed in consideration of the spatiotemporal and spatial correlation of the video signal. The encoded video signal is restored to the original signal before encoding using a decoding technique such as variable length decoding, inverse DCT, inverse quantization, and motion compensation, and the recovered digital video signal is transferred to the next video encoding block 106. Is provided.

Next, the video encoding block 106 converts the tuned digital video signal provided in the MPEG decoding block 104 described above into an NTSC or PAL analog video signal and then to the contact b of the switching block 114 via the line L13. to provide.

In addition, the video processing block 108 processes the tuned analog video signal (i.e., cable broadcast channel signal) provided by the tuner block 102 through line L14, e.g., level amplification, noise cancellation, gain control. Various signal processing such as the above is performed and provided to the contact point c of the sync extraction block 110 and the switching block 114 through the line L15.

Meanwhile, the sync extraction block 110 extracts a sync signal, that is, a horizontal sync signal, included in the tuned channel signal provided by the video processing block 108 through the line L15, and the extracted horizontal sync signal is Provided to control block 110 via line L16. In this case, the horizontal sync signal extracted here is used to determine whether the tuned broadcast signal is an effective channel. The existence of the horizontal sync signal is checked for each channel so that only a channel with good viewing can be automatically tuned. It will be performed for a predetermined time.

On the other hand, the control block 112 is, for example, a microprocessor that performs overall operation control of the receiving system, and when the user broadcast channel selection signal (ie, operation signal) is input from the outside, the corresponding tuning control signal Is generated and provided to the above-described tuning block 102 through the line L11, and stores channel information (effective channel) of each broadcast mode (satellite broadcast mode and cable broadcast mode) in the area A of the memory block 114.

In addition, in the region A of the memory block 114, various OSD data for displaying various menu screens and guide screens, in addition to the channel information described above, are stored. In the region B, reservation information set by a user is stored.

When the control block 112 sends out a message or a guide screen to a monitor (not shown), the OSD data is extracted from a predetermined area of the memory block 114 to the OSD processing block 116 through the line L18. Will be provided.

In addition, the control block 112, based on the user operation signal from the outside, the switching control signal on the line L17 for switching the output of the broadcast signal corresponding to the broadcast mode currently being viewed or the broadcast mode that the user wants to switch To the switching block 120 to be described later.

The OSD processing block 116 displays the OSD screen data based on the vertical and horizontal sync signals generated for positioning of the OSD data to be sent when the message data is provided from the control block 112 through the line L18. And the OSD screen data configured here is provided to the mixer 118 via line L19.

Therefore, the mixer 118 properly mixes the image data on the line L15 and the OSD screen data when the OSD screen data is provided through the line L19 to provide the contact c of the switching block 120 through the line L20. Also, the mixer 118 bypasses the image data on the line L15 to the contact c of the switching block 120 as it is when there is no OSD screen data on the line L19.

Meanwhile, the switching block 120 selectively switches the video signal output of the tuned cable broadcast (or a mixed video signal mixed with OSD data) and the video signal output of the tuned satellite broadcast channel, and the control block described above through the line L17. Based on the switching control signal provided from 112, when the satellite broadcast mode is selected by the user, the contact ab is connected to provide a video signal of the satellite broadcast channel provided through the line L13 to the display side, not shown, and When the cable broadcast mode is selected, the contact ac is connected to provide a video signal (or a mixed video signal mixed with OSD data) provided through the line L20 to the display side, not shown.

On the other hand, unlike the satellite broadcast signal described above, the general CATV broadcast signal does not include channel information (channel name) for each channel, so that it is difficult for a user to distinguish a plurality of CATV channels. Therefore, the user must go through the process of inputting each channel name of the CATV directly to the desired channel name.

FIG. 2 is a diagram for explaining a process of directly setting a channel name of each CATV by the user, which will be described below with reference to the accompanying drawings.

First, when a user operates a key input means (not shown) to input each channel name of the CATV, and the CATV channel guide key signal is input, the control block 112 activates the CATV stored in the A area of the memory block 114. By reading the channel information and the OSD data and providing them to the OSD processing block 116, the CATV channel guide screen as shown in FIG. 2A is displayed.

Then, the user selects a specific channel of CATV by referring to the displayed guide screen and directly inputs a channel name for the corresponding channel. As shown in the drawing, the user selects 'CH 3' by operating a key input means. If so, the channel name change menu screen shown in FIG. 2B is displayed by the control block 112 again.

At this time, when the user inputs a new channel name (for example, 'KBS 1') for the corresponding channel by using the key input means, the input new channel name is stored in the A area of the memory block 114 to enable the validity of CATV. The channel information is updated, and the currently displayed channel name input menu screen is turned off and the updated CATV channel guide screen is displayed as shown in FIG. 2C.

In addition, the user may repeat the above-described process to input a new channel name for each of the other channels of the CATV. Each channel for which the new channel name is not set by the user is illustrated in FIG. 2C. Only the original channel number is taken.

After the channel names of the CATV set by the user are stored in the A area of the memory block 114 through the above process, when the reservation for the specific channel of the satellite broadcast and the CATV broadcast is set by the user, the control block 112 determines this. It is stored in the area B of the memory block 114 again.

On the other hand, if the key signal for displaying the reservation guide screen by the user's key operation is input in the state that the channel name and the reservation information of the CATV is preset through the above-described process, the control block 112 is a memory block 114 By reading the OSD guide screen data stored in the area A and the reservation information stored in the B area and providing them to the OSD processing block 116, the reservation guide screen as shown in FIG. 3A is displayed on a monitor not shown.

That is, as shown in the drawing, the reservation list 301 for each channel set by the user and the program title 303 for the reservation information on which the cursor is currently positioned are displayed. In the displayed initial state, the cursor is automatically positioned at the first reservation information.

Therefore, when the reservation guide screen is displayed by the user's operation signal, the control block 112 determines whether the channel of the reservation information located first in the reservation information stored in the area B of the memory block 114 is the satellite broadcast channel. In the case of the satellite broadcasting channel, the channel information and program information stored in the area A of the memory block 114 are read, and the program title broadcast in the corresponding time zone of the corresponding channel is read. And display at 303.

On the other hand, in contrast, when it is determined that the channel of the reservation information located first is the CATV broadcast channel, the control block 112 includes channel information (for example, KBS 1, GOLF, CATV, etc.) included in the reservation list 301. Is displayed in the program title field 303 as it is. That is, since additional information is not provided to the CATV broadcast signal other than the broadcast signal for each channel, the channel information set by the user is displayed in the program title column 303.

When the reservation guide screen based on the user's operation signal is displayed through the above-described process, when the user operates the key input means (not shown) to move the cursor displayed on the screen, the control block 112 Again, it is determined whether the channel of the position where the cursor is moved is a satellite broadcasting channel or a CATV broadcasting channel. If the position of the cursor is moved to the CATV channel as shown in FIG. 3B, the control block 112 is moved to the same view. As shown, the channel information set by the user, that is, 'KBS 1' is displayed in the program title field 303.

That is, when the moved cursor is located on the CATV channel in the reservation list, the additional information such as the title of the program is not provided in the CATV broadcast signal, so that the user inputs the reservation information by displaying the channel information input by the user. Make it easy to recognize.

Meanwhile, FIG. 4 is a flowchart illustrating a process of displaying a reservation guide screen of a composite broadcast receiver according to an exemplary embodiment of the present invention. Hereinafter, the above-described process will be described in detail with reference to the accompanying drawings.

When the reservation information set by the user is stored in the area B of the memory block 114 (step 401), when an operation signal for displaying the reservation guide screen is input again by the user (step 403), the reservation as shown in Fig. 3A is made. The guide screen is displayed (step 405).

In this case, the control block 112 determines whether the channel on which the cursor is located, that is, the first reserved information channel is a CATV channel (step 407). In step 417, the title is extracted from the region A of the memory block 114 in the broadcast program of the reserved time zone and displayed in the program title field 303 of the guide screen.

On the other hand, on the contrary, as a result of the determination in step 407 described above, when the channel where the cursor is currently located (that is, the channel for the first reservation information) is a CATV channel, the channel information displayed in the reservation item of the guidance screen is displayed on the guidance screen. Is displayed in the program title field 303 (step 411).

If the user moves the cursor again by operating the key input unit (not shown) while the reservation guide screen corresponding to the reservation guidance screen key signal of the user is displayed (step 413), the control block ( 112 again determines whether the reservation information channel corresponding to the position where the cursor is moved is a CATV channel or a satellite broadcasting channel, and repeats the above-described step 409 or 411 according to the determination result. .

On the other hand, if the key signal for moving the cursor is not input in step 413 described above, and a predetermined time elapses or a key signal for turning off the guidance screen is input (step 415), the control block 122 The reservation guidance screen currently displayed is automatically turned off (step 419), and the operation of the receiver is switched to the normal viewing mode before the reservation guidance screen key signal of step 403 described above is generated (step 421).

As described above, according to the present invention, a reservation guide screen displaying reservation information of a composite broadcast receiver capable of receiving a satellite broadcast signal and a CATV broadcast signal is displayed by displaying the CATV channel information set by the user together with each reservation information item. In addition, there is an effect that can provide convenience to the user to confirm the reservation information, and there is an effect that can satisfy the needs of various users accordingly.
